Abstract
The Phantom cell concept is a solution for high-traffic outdoor environments that can also support good mobility and connectivity in ultra-dense network. In a phantom cells network, a centralized Macrocell controls all phantom cells within its coverage area and the C-Plane and U-Plane are split. Many issues need to be addressed for this architecture including radio resources allocation and cross/co tier interference mitigation. One of effective techniques used to mitigate interference is to group the cells in community (clusters). In this line, we propose a review of the max-min distance algorithm to establish the optimal cluster number, which affects significantly the system performance. Also, to assign the spectral resources to cells of the cluster, a new allocation algorithm based on traffic demand is proposed.
